Description

Technical Field

[0001] This utility model relates to the field of environmental protection and dust removal technology, specifically to an environmental protection dust removal device for feeding and unloading materials and a raw material quality detection system. Background Technology

[0002] Raw materials for building material production lines such as concrete mixing plants, dry-mixed mortar, manufactured sand, and silt brick making typically arrive at the site via dump trucks, unloading directly into the stockpile. From there, they are transferred a second time by loaders into inline aggregate bins, or dump trucks directly unload into ground-level unloading hoppers. Inline aggregate bins or ground-level unloading hoppers are usually open-designed, resulting in uncontrolled dust emissions during the feeding and unloading process, polluting the plant environment. Even in simply enclosed structures, dust permeates the enclosed space, creating harsh working conditions that seriously endanger the health of back-end material handling and quality control personnel. Furthermore, the use of visual or radar detection to identify the type, particle size, and particle shape of raw materials requires a low-dust testing environment. High-dust environments cannot meet the cleanliness requirements of raw material quality testing equipment. Therefore, an environmentally friendly dust removal system for feeding and unloading is urgently needed to achieve clean production in the back-end material yard area. Utility Model Content

[0003] The purpose of this utility model is to provide an environmentally friendly dust removal device for feeding and unloading and a raw material quality testing system to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An environmentally friendly dust removal device for feeding and unloading materials includes:

[0006] The silo is equipped with a discharge port for unloading from a material cart. Side doors that open and close horizontally are provided on both sides of the discharge port, and a vertical door that opens and closes vertically is provided on the top of the discharge port. The side doors and the vertical door are used to bring the material cart closer during unloading to reduce dust escape. A dust concentration sensor for controlling the air volume of the dust collector is also installed inside the silo.

[0007] A dust collector, wherein a dust collection pipe is connected to the air inlet of the dust collector, and the end of the dust collection pipe is located at the top of the silo and is equipped with a dust suction hood;

[0008] A water mist dust suppression system is used to suppress dust in the silo.

[0009] Preferably, both the side door and the longitudinal door are sensor doors, forming a double-sealed door with inner and outer layers, wherein the side door operates on an upper track.

[0010] Preferably, a steel cable is installed inside the upper track, and a drive motor is fixedly installed on the side of the upper track away from the unloading port. The drive motor controls the opening and closing of the side door by moving the drive steel cable.

[0011] Preferably, a distance sensor is fixedly installed at both the side door and the longitudinal door. The distance sensor is used to control the silo door to move closer to the material cart to prevent dust from escaping.

[0012] Preferably, the dust concentration sensor is fixedly installed on the top of the silo near the dust collection hood, and an electronic camera is also fixedly installed next to the dust concentration sensor. The camera is used to monitor the position of the material cart and the raw material quality parameters.

[0013] Preferably, the water mist dust suppression system includes a security filter, a resin tank, and an atomizing host connected in sequence. The resin tank is also connected to a salt tank for regenerating the resin. The atomizing host is connected to an atomizing pipe, which extends to the top of the hopper. The water mist dust suppression system is used to suppress dust and clean the camera surface regularly to maintain clear images.

[0014] Preferably, the filter bag material of the dust collector is made of hydrophobic fiber, which has the ability to handle dust with a certain humidity.

[0015] This solution also provides a raw material quality testing system, which uses the feeding and unloading environmental protection dust removal device described in any of the above-mentioned embodiments.

[0016] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0017] This solution automatically adjusts the size of the feeding port by setting up side and longitudinal doors and using distance sensors to reduce its open space and prevent dust from escaping. It also closes the corresponding pipes at non-unloading positions and opens the corresponding channels at feeding positions by using airtight air valves. At the same time, the dust concentration sensor adjusts the flow rate of the dust collector fan to achieve efficient dust removal.

[0018] This solution uses a water mist dust suppression system that is activated during unloading to aggregate ultrafine dust, effectively suppressing dust in the silo. In addition, this solution is combined with a dust collector to further improve the cleanliness of the exhaust gas, greatly enhancing the overall dust removal efficiency.

[0019] This solution uses cameras and external systems to effectively identify raw material parameters and provide real-time quality data such as raw material type, particle shape, and particle size. At the same time, the efficient dust removal of the dust collector and water mist dust suppression system ensures the accuracy of the camera monitoring images. Attached Figure Description

Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0030] When the material cart 4, fully loaded with raw materials, approaches the silo 1, the corresponding silo door automatically opens to its maximum. After the material cart 4 arrives in position, the distance sensors 15 on both sides and the top provide the outline position of the material cart 4. The external system then controls the side doors 12 and the longitudinal doors 14 to move closer to the target outline, reducing open space and preventing dust from escaping. Unloading begins, and the camera 24 and dust concentration sensor 23 provide signals. The external system then controls the dust collector 2 to start and adjusts the airflow according to the dust concentration. Simultaneously, the water mist dust suppression system 3 starts, working in conjunction with the efficient operation of the dust collector 2 to effectively remove dust, providing the necessary conditions for monitoring and analyzing the raw material quality parameters.

[0031] After introducing the basic principles of this utility model, various non-limiting embodiments of this utility model are described in detail below. Any quantity of elements in the accompanying drawings is for illustrative purposes only and not for limitation, and any naming is for distinction only and has no limiting meaning.

[0032] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0033] Example 1

[0034] An environmentally friendly dust removal device for feeding and unloading materials and a raw material quality testing system, such as Figure 1-6 As shown, the device includes a silo 1 and a dust collector 2. The silo 1 is provided with a discharge port 11 for unloading material from the material cart 4. The dust collector 2 is connected to a dust collection pipe 21 at its air inlet. The end of the dust collection pipe 21 is located at the top of the silo 1 and is provided with a dust suction hood 22.

[0035] like Figure 2-5 As shown, symmetrical side doors 12 are installed on both sides of the discharge port 11. The side doors 12 operate on an upper track 13, which is fixedly installed on the top wall outside the discharge port. In this embodiment, the side doors 12 are driven by a drive structure 16, which includes a transmission wheel 161, a steel cable 162, a fixing block 163, a sliding block 164, and a drive motor 165. The steel cable 162 is installed inside the upper track 13, and the top of the side door 12 is slidably mounted on the steel cable 162 via the sliding block 164. The top of the side of the side door 12 used for closing is fixedly connected to the steel cable 162 via the fixing block 163. In addition, the drive motor 165 is fixedly installed on the side of the upper track 13 away from the side door 12 when it is closed. The drive motor 165 drives the transmission wheel 161 to rotate in both directions, drives the steel cable 162 to move, and then drives the fixing block 163 and the sliding block 164 to move, thereby controlling the opening and closing of the side door 12. In other embodiments, the drive structure 16 may also be a lead screw nut or an electric cylinder, which drives the side door 12 to slide open and close along the upper track 13.

[0036] A longitudinal door 14 is fixedly installed on the top of the unloading port 11. The side door 12 and the longitudinal door 14 form a double-layered sealed door, one on the outside and one on the inside. In this embodiment, both the side door 12 and the longitudinal door 14 are automatic sensor doors. The side door 12 is a sensor-operated stacking door, and the longitudinal door 14 is a sensor-operated roller shutter door that opens when the material cart 4 approaches. Both are existing technologies and will not be described in detail here. In other embodiments, the side door 12 can also be a sliding automatic sensor door.

[0037] like Figure 2-5As shown, distance sensors 15 are fixedly installed at the side doors 12 on both sides and the top longitudinal door 14 on the top. Specifically, the distance sensors 15 can be installed in front of the unloading port 11 or on the wall around the unloading port 11. They are used to detect the outline of the material cart 4 during unloading, and then control the side doors 12 and the top longitudinal door 14 to move closer to the target outline via an external system, reducing open space and preventing dust from escaping. In this embodiment, the distance sensor 15 is a radar distance sensor 15 or an infrared distance sensor 15.

[0038] A dust concentration sensor 23 is fixedly installed on the top of the hopper 1. The dust concentration sensor 23 is located near the dust collection hood 22 and is used to detect the dust concentration and control the airflow of the vacuum cleaner. An electronic camera 24 is also fixedly installed next to the dust concentration sensor 23. The camera 24 is used to monitor the position of the material cart 4 in real time and is connected to an external system to analyze the raw material quality parameters.

[0039] like Figure 3 and Figure 6 As shown, a water mist dust suppression system 3 is also fixedly installed on the top of the silo 1. The water mist dust suppression system 3 includes a security filter 31, a resin tank 33, and an atomizing host 34 connected in sequence. The resin tank 33 is also connected to a salt tank 32, which is used to regenerate the resin after it becomes saturated and to continuously provide softened water. The outlet of the atomizing host 34 is connected to an atomizing pipe 35, which extends to the top of the silo 1 and is fixedly installed. Tap water passes through the security filter 31, the resin tank 33, and the atomizing host 34 in sequence, and is finally sprayed out from the atomizing pipe 35 at the top of the silo 1 in the form of high-pressure water mist. This ensures that the water mist can cover the entire silo 1, quickly gather dust particles, and facilitate rapid filtration by the dust collector 2. In addition, the pipe installed at the top of the silo 1 is located above the camera 24 to avoid the water mist forming from obscuring the image of the camera 24. At the same time, the high-pressure water mist can also be used to periodically clean the surface of the camera 24 to maintain image clarity.

[0040] The aforementioned security filter 31, resin tank 33, salt tank 32, and atomizing host 34 are all common devices in the industry and are existing technologies, so they will not be described in detail here. The atomizing host 34 is shown in patent CN219971895U.

[0041] Dust collector 2 is existing technology equipment. The filter bag material of dust collector 2 is made of hydrophobic fiber, which has the ability to handle dust with a certain moisture content. The dust collection pipe 21 connected to the air inlet of dust collector 2 can branch out into multiple branch pipes, each corresponding to a hopper 1, so as to realize the simultaneous feeding and unloading of multiple hoppers 1 for dust collection. The end of each branch pipe is equipped with an electric airtight valve (not shown in the figure, which is existing technology, such as patent CN222163594U). By controlling the opening and closing of the electric air valve, the dust collection process of different hoppers 1 can be controlled, making it more convenient and flexible to use.

[0042] The dust collector 2, side door 12, longitudinal door 14, distance sensor 15, camera 24, dust concentration sensor 23, drive structure 16, electric air valve, and water mist dust suppression system 3 are all electrically or wirelessly connected to an external system. Through the control of the external system, stable operation of unloading and dust removal is achieved. The specific process includes: when the material cart 4 is fully loaded with raw materials and approaches the unloading port 11 of the silo 1, the side door 12 and longitudinal door 14 of the corresponding silo position sense the vehicle and automatically open to the maximum. After the material cart 4 arrives, the distance sensors 15 on both sides and the top of the unloading port 11 give the outline position of the material cart 4, and through the external system, the side door 12 and longitudinal door 14 are controlled to move closer to the target outline to reduce the open space and prevent dust from escaping during unloading. When unloading begins, camera 24 monitors vehicle information and sends a signal, or dust concentration sensor 23 senses dust and sends a signal. The external system then controls dust collector 2, and the corresponding electric air valve and water mist dust suppression system 3 in hopper 1 are activated to effectively remove dust from hopper 1. During dust removal, the external system adjusts the airflow of dust collector 2 in real time according to the dust concentration measured by dust concentration sensor 23 to achieve efficient dust removal.

[0043] In addition, camera 24 is also used to monitor the quality parameters of raw materials. By monitoring the dynamic images of raw materials in real time during the unloading process and combining them with big data from external systems, the raw materials are judged and the quality data such as the type, particle shape and particle size of the raw materials are given in real time. At the same time, the efficient dust removal of dust collector 2 and water mist dust suppression system 3 also ensures the accuracy of the monitoring images of camera 24, providing basic data guarantee for high-quality concrete production.

[0044] The above-described preferred embodiments of the present invention are provided for guidance, but it will be apparent to those skilled in the art that such embodiments are provided merely by way of example. Many modifications, alterations, and alternatives will arise in the mind and spirit of the present invention without departing from its intent. It should be understood that various alternatives to the embodiments of the present invention described herein may be employed in the practice of the present invention. The appended claims are intended to define the scope of protection of the present invention and therefore cover the modular compositions, equivalents, or alternatives within the scope of these claims.
